scientists and delegates at a un climate conference in poland have expressed alarm, after it failed to incorporate a key scientific text, which outlines how to limit the affects of climate change. the ipcc report on the impact of a 1.5 degree celcius temperature rise was released in october. but now the us, russia, saudi arabia and kuwait have objected to the conference ‘welcoming' it. caroline rigby has more. chanting: wake up! wake up! as delegates met inside the conference centre, thousands marched outside, demanding politicians wake up to the threat of climate change, voicing concerns that time is running out. we need to do something now, we need action right now. not tomorrow, not in 11 years, but now. and yet another spanner in the works — one which threatens to derail

progress on tackling global warming. in october, the un's intergovernmental panel on climate change detailed the importance of keeping global temperature rise to under 1.5 celsius. in a major report, it warns we have just 12 years to halve carbon emissions or risk significant and dangerous changes to our world. and despite being commissioned by this very un climate body at its conference in 2015, efforts to recognise the report's significance have run into difficulty. saudi arabia, the united states and russia have refused to welcome the text, merely wanting to take note of it instead and without finding an acceptable compromise, un rules meant it had to be dropped. this is far from just semantics. it has the potential for major consequences and is further evidence of the growing divide between countries who want rapid political action and those who do not. it's an important report. it should be part of the package

that is moving forward but again, it's up to the world leaders and the negotiators to take this issue seriously and to show that they are committed to tackling climate change. the decision to reject the text has caused outrage among delegates but against the backdrop of this coal mining town, all may not be lost. many at the summit are now pinning their hopes on ministers who arrive on monday to work towards the reinstatement of the report. caroline rigby, bbc news. a little earlier i spoke to michael mann, professor of climatology at pennsylvania state university. i asked him exactly why these countries are objecting to the report. we have seen this story before. a small number of bad actors who in essence are conspiring to prevent the implementation of an agreement where there is otherwise support among the rest of the world's nations. in this case, the conclusion that we need to keep warming below 1.5 celsius and that requires

substantial reductions in carbon emissions over the next ten or 12 years. we have to bring them down by about 50% within the next 12 years if we are going to stabilise a warming below that dangerous level of warming, and here you have the united states, of course the trump administration which has been very cosy with fossil fuel interests, trump had appointed the former ceo of exxon mobil to be his former secretary of state. so clearly fossil fuel interests are running the trump administration. saudi arabia of course driven by fossil fuel interests and then russia which has attempted a half a trillion dollar deal with exxonmobil to mine the remaining oil reserves in russia. you have three actors conspiring, some might say colluding, to basically get in the way of this very important agreement.

the ipcc report recommended some far reaching changes, especially in the way we use our energy. it was quite profound at the time. isn't this the report hitting up against reality? there are a couple of countries here like saudi arabia and kuwait, their entire economic model, practically, arguably, is fossil fuels. yeah but there are countries that have historically been fuelled by the fossil fuel industry that recognise that there is a transition under way. we are leaving the age of fossil fuels. those countries that get on board with the greatest economic revolution of this century, renewable energy revolution, are the ones that are going to succeed going forward. so at this point, those countries have to decide if they are going to get on board with this transition, with this economic revolution,

or if they are going to get left behind at the station and unfortunately, a small number of countries, the trump administration of course currently controlling us policy, russia and saudi arabia are instead focused on their own short—term financial interests at the expense of the larger interests of this planet. much more on our website with more in—depth coverage. downing street insists that tuesday's crunch brexit vote will go ahead despite reports that theresa may wants to delay it. the prime minister has warned that the uk would be in "uncharted waters" if mps fail to back the bill, while the conservative peer lord heseltine says that "true british patriots" would join him in demanding a so—called people's vote. our political correspondent iain watson has more. all week arguments have raged about

accept and theresa may's deal. today, they are being taken to the streets, a large conference centre in east london. if you are someone who supports the people's vote campaign, they are having a rally for another wrap and. there will be a range of celebrities. it will be arguing that it is true british patriots that want another referendum. other —— the lead campaigners are believing they are reducing britain's influence. not to be outdone, ukip is organising its own rally, a brexit betrayal rally, they are calling it. it will also include the controversial figure of tommy robinson used in the in the ingush defence league and whose presence have caused a few in ukip, including nigel farage, to resign from the party. not surprisingly, there will be a counter demonstration. theresa may will be focusing on winning over more of her

mps for her deal. she has an uphill battle before the vote on tuesday. downing street are insisting that votes will go ahead despite the fact that the speculation at westminster is she will lose a quite substantially. if anything, things seem substantially. if anything, things seem to be going slightly in the wrong direction for her because last night a junior ministerial aide resigned saying he couldn't back her deal. this is a time when she really needs to win people over. again, ministers are being talking more openly about what might happen if the deal doesn't go ahead. donald trump is searching for a new chief of staff after announcing that john kelly will leave the white house at the end of the year. the retired marine corps general was first homeland security secretary before stepping up to the chief of staff job last year. the president says a replacement will be announced sometime over the weekend — but the news has highlighted yet again the frequent senior staff changes at the white house. russell trott reports. if you want to get things done and impose discipline then

who better to fill the role of the president's chief of staff than a retired marine corps general? john kelly certainly fitted the bill but the white house faces a fresh challenge in the new year when the democrats take control of the house of representatives so a new approach is needed. sojohn kelly will be leaving toward the end of the year, at the end of the year, and i appreciate his service very much. telling the president things he might not want to hear can, for any member of staff, result in a difficult relationship. a year ago general kelly had jokingly denied reports that he clashed with his commander in chief. i willjust offer to you that although i read it all the time,

pretty consistently, i'm not quitting today. (laughter). i don't believe and ijust talked to the president, i don't think i'm being fired today. and i'm not so frustrated in this job that i'm thinking of leaving. also nominated for a new role is a—star army general mark milley to be the next chairman of the joint chiefs of staff. his follows nominations for a new attorney general and a new ambassador to the united nations. according to one washington think tank, the trump white house has had the highest turnover of senior level staff of the past five presidents. the revolving door, it seems, will keep on turning. russell trott, bbc news. a show of strength from police thwarted escalating violence during a fourth weekend of anti—government protests in france. riot squads fired rubber bullets and tear gas at demonstrators to gain the upper hand after ugly clashes in the capital. nearly 1,000 people were arrested across the country, as lucy williamson reports. they called it a protest. at times it looked more like a game of urban war. groups of protesters fanned through the capital's streets today.

from the arc de triomphe to republique, boulevards once built to open the veins of the city filled with tear gas, burning vehicles, and riot police. on the champs—elysees this morning, the mood was largely peaceful. protesters arriving here from across france caught up inafamiliardance of conflict with police. police are just pushing the protesters back down out of this side street onto the champs—elysees. the police were well prepared for this confrontation, with armoured vehicles, new tactics, and bag searches — seizing gas masks and helmets and anything that could be used against police. the tear gas, far stronger than usual, took many protesters by surprise. and rapid reaction squads marked out by orange armbands were stationed among the protesters to spot trouble and make early arrests. despite the violence of previous protests, this movement still has the backing of many voters in france.

its members proud of their lack of leadership and the diversity of their support. but this movement is already splintering into two kinds of protest — one that looks towards a new political programme and a violent wing, opposed to any negotiation. it is hard to exclude and even harder to control. lucy williamson, bbc news, paris. police in new zealand investigating the murder of the british backbacker, grace millane, say they've found a body. they had been searching bushland about 2k kilometres west of auckland. police they say they want to trace a toyota corolla which was hired last week. a 26—year—old man is due to appear in court on monday, charged with her murder. police held a news conference near to where the search took place. this morning we have had a senior examination behind me in the bush behind me. this area was identified late —— late last night as a result of our investigative work was stock ican of our investigative work was stock i can now advise that a short time ago relocated a body which we believe to be grace. the formal

identification process will now take place however based on the evidence we have gathered over the past few days, we expect that this is grace. obviously this brings a search for grace to an end. it is a number of full—time for the family and our hearts go out to them. stay with us on bbc news, still to come: a museum lifting the lid on belgium's colonial past comes under attack for showcasing stolen treasures. john lennon was shot at the entrance to the dakota building, in the centre of new york. there's been a crowd here, standing in more or less silent vigil, and the flowers have been piling up. the 14th ceasefire of this war ended at the walls of the old city of dubrovnik. this morning, witnesses said shells were landing every 20 seconds. people are celebrating the passing of a man they hold responsible

for hundreds of deaths and oppression. elsewhere, people have been gathering to mourn his passing. imelda marcos, the widow of the former president of the philippines, has gone on trial in manila. she's facing seven charges of tax evasion. she pleaded not guilty. the prince and princess of wales are to separate. a statement from buckingham palace said the decision had been reached amicably. this is bbc news. the latest headlines: dismay at the un climate talks after several countries include the us and russia object to a major report on global warming. the british prime minister tells rebels in her government that they risk losing power unless they back her brexit deal. voters are going to the polls in armenia —

china has warned canada that there will be severe consequences if it doesn't release huawei's chief financial officer meng wanzhou. ms meng was arrested in vancouver a week ago following an extradition request from the united states. authorities there have accused her of fraud in connection with alleged breaking of american sanctions on iran. china's foreign ministry has summond canada's ambassador, calling the arrest ‘extremely nasty‘. professor paul evans is from the institute of asian research at the university of british columbia in vancouver and an expert on relations between canada and china. he says there are several ways that china could try to pressure canada. the pressure could come in several forms and i think it is very likely that there will be not a tit—for—tat retaliation in any way but some limitations on incoming chinese investment into the country and also reduction of research and development funds that huawei and other chinese companies are putting here. they are pushing...

this is something that puts canada in the middle of a crossfire between the united states and china. to some extent, china understands the pressures but also the rules that control extradition proceedings between the us and china. and finally this is a very difficult issue for huawei because canada is one of the countries still considering major huawei investment in our 5g system. so there is a natural reaction to this at the same time the calculation may be to wait and see how the hearings move and then the extradition hearings that will start sometime shortly thereafter. you talk about crossfire

between china and the united states. i want to hear if canada is a victim in all of this, that really this is about china and the united states. i don't think this is a situation that ottawa wants to be in the middle of. we have not yet determined exactly how far we want to join the united states in its decoupling from particular sectors in china. ottawa would have preferred this not to have happened but it was locked into place by our security agencies in cooperation with americans. and under the due process of law in canada, our political people did not get involved. i think it is fair to say that no—one in ottawa wished this kind of controversy to take place right now on canadian soil. in terms of china's internal politics,

it is there an element of china trying to save face? it will, in this particular case, because i think the fear is that this could be a precedent for other kinds of arrests and extradition proceedings, not just in canada, but in several other countries as the trump administration is ramping up its conflict and trade war. but underneath it, it is really a technology war. this opens up the possibility of many kinds of activities like this. and that will escalate things very seriously on the us—china front and catch a number of other countries like canada in the crossfire of what is a very unfortunate and fast deteriorating situation. that was professor paul evans

speaking to me earlier. voters are going to the polls in armenia — in the first parliamentary elections since a peaceful revolution in the former soviet country earlier this year. the elections were called by the acting prime minister nikol pashinyan. he is seeking to consolidate his authority after sweeping to power and to secure an outright majority to carry out ambitious political and economic reforms. our correspondent, rayhan demytrie, is in the armenian capital yerevan and joins me now. pashinyan swept to power, he was prime minister. why take this risk in calling a snap election? although pashinyan became prime minister of the back of mass protests, extraordinary events that happened here in april and may this year, the

parliament, the armenian national assembly has been dominated so far by mps representing the former governing party. and this is what pashinyan is hoping to now change. he wants to, he is predicted to win ina he wants to, he is predicted to win in a landslide victory. he is enjoying massive support from the population at the moment and this is something that he has been criticised for by his opponents. there are 11 political parties taking part in this election but other parties have complained. they say they did not get enough time to organise for campaigning. they have also accused mr pashinyan of abusing the euphoria that is still very much present in armenia, to use that to get more votes and more paolo.|j present in armenia, to use that to get more votes and more paolo. i can see there that you seem to be at the polling station. i wonder what are some of the projections that you think mr pashinyan will sweep to

power? this is what has been predicted by the polls. yesterday we we re predicted by the polls. yesterday we were doing our own vox pop in the street of the capital. i would say that the majority of people, they are quite inspired by the armenian leader. they trust and believe him. i asked why they liked him so much and they say because he is honest and they say because he is honest and has changed the way he talks to the people. he uses a lot of social media, facebook and whenever there isa media, facebook and whenever there is a big issue that comes up in the country he directly talks to people via social media. again, his opponents are saying that he is a populist and he is using this post revolutionaries euphoria to win a majority in parliament. thank you very much. we will keep you across the latest when the polls close. belgium's royal museum for central africa opens its doors to the public again on sunday

after being shut for several years of renovation. it's home to many treasures — though there is controversy surrounding much of what it holds. rebecca hartmann reports. artwork, statues and stuffed animals will once again be available for visitors to see in the africa museum. many of these treasures on display were plundered during belgiam's ruthless colonial rule. swathes of central africa were run as a private royal estate by belgian king leopold ii. the museum began as a showcase of their treasures. but in the past five years, it has been revamped to make its exhibits more critical of belgiam's brutal colonial past. translation: we were often called the last colonial museum in the world, so we wanted to change that. we wanted to look at contemporary africa, but at the same time, take a more critical look at the colonial past. it's estimated that around 90% of africa's material cultural heritage is in museums outside of the continent.

so, for many, the renovation does not go far enough. translation: from our point of view, we don't care if the museum is renovated or not, if it reopens or not. what interests us is restitution, because there's no decolonisation without restitution. the debate over returning artefacts has raged for years. but it is only recently that the former imperial powers have started to address the requests. president macron urged that artefacts stolen by france should be returned after commissioning an independent report. and several european museums, such as victoria and albert museum in london, have said that treasures like these, taken from ethiopia by the british, could be returned to africa on a long—term loan. we're willing to talk about restitution within certain conditions. like, we need to establish the ownership, who owns it. clearly, the moral ownership is with the country. but does it mean that everything that was acquired in the colonial period is legal or not? so, that needs to be discussed further. whatever happens, after five years

out of the public view, it's hoped that these artefacts will gain a wider audience. rebecca hartmann, bbc news. now to a museum that's managed to repatriate its missing treasure....fragments of one of turkey's most striking mosaics, dating back to the time of alexander the great, have returned home. half a century ago they were plundered and smuggled to the united states, as gail maclellan reports. haunting and ancient — the 2000—year—old image of the gypsy girl whose piercing stare has become the symbol of a city in southern turkey. she lived in a mosaic, pieces of which were looted in the 1960s and smuggled to the united states where they were bought by bowling green state university in ohio. 20 years ago, archaeologists excavating the city of zeugma, destroyed in the third century, discovered the mosaic and the theft of the fragments. the smuggled pieces had been

on display at the university, and after five years of talks, an agreement was reached and they were returned to turkey. now, the fragments have gone on temporary show at the zeugma mosaic museum in the place where the city flourished under greek and roman rule before it was destroyed. later, they'll be pieced together, back into their original place in the mosaic, and the gypsy girl will finally be reunited with herfamily. gail maclellan, bbc news. you can reach me on twitter — i'm @regedahmadbbc. good morning. saturday was a windy,

showery day for many of us, and there's still plenty of showers to come, with the winds still remaining a feature. but they are slowly going to ease over the next few hours, and for the bulk of us on sunday, it will be a dry one with sunny spells, but noticeably cooler. now, the strongest of the winds over the next few hours will slowly start to ease, but we still could potentially see gale—force gusts in places and a rash of showers to come as well. one of the reasons why they're going to ease away is due to a change of wind direction, starting to push that little frontal system further south in the early hours of sunday morning. introducing some colder air behind it, the wind direction coming from a north—westerly. so, we could have some early showers, they will ease away and it's an improving picture as we go through sunday. clearer skies and, yes, some sunny spells coming through. a few showers into north wales and northern ireland during the afternoon, maybe one or two for the western isles, not as windy as the last few days, but you have to factor in the direction of the wind, because that's just going to make it feel cooler out there. 6 to 7 degrees in the north,

we mightjust see 11 down into the south—west. overnight sunday night, we keep those clear skies and the winds falling lighter still. so, temperatures are likely to fall away, particularly in the northern half of the country. scotland, northern england, we will see temperatures falling below freezing in rural spots, and there will be a frost first thing. a chilly start generally across the country. a cold start to the new working week, but a dry, bright one, again, some sunshine coming through, just a few isolated showers out to the west. this is going to be the trend as we move into the week. so, the best of the drier, sunnier weather is likely to be sheltered eastern areas, but that's where the coolest of the weather is going to be. 4—6 degrees, 10—12 the high further west. this is going to be the theme. to the east, we're always going to be dragging in this colder air from the near continent, but the west wants to drag back this milder air and the south—westerly winds,

and that could also bring more unsettled weather with it. so, we see this again on tuesday, a southerly wind drives in this weather front, and further east, the drier the brighter, but the colder the weather is likely to be. 4—6 degrees again the high, 10—12 into the south—west. and it does look as though further ahead, we start to see that milder weather pushing its way in. as that bumps into the cold air, it could get a bit tricky with some wintery weather to higher ground. this is bbc news, the headlines: there's dismay at the un climate talks after the us, russia, saudi arabia and kuwait, objected to a major scientific report on global warming. the report recommends that carbon emissions be halved over the next twelve years to keep the global rise in temperatures under 1.5 degrees celsius. britain's prime minister has warned rebels from her own governing party that they risk losing power and remaining in the european union if they fail to back her brexit deal.

theresa may has made the comments in a newspaper interview, ahead of a crucial parliamentary vote on tuesday. police in new zealand investigating the murder of the british backbacker, grace millane, say they've found a body. they'd been searching bushland about 2k kilometres west of auckland. a 26—year—old man is due to appear in court on monday, charged with her murder. now on bbc news, the week in parliament.
